Activision Sets Call of Duty: Modern Warfare 4 Beta for August 21 Early Access and August 28 Open Weekend

Activision has announced the beta schedule for Call of Duty: Modern Warfare 4. Early access for players who preorder will run from August 21 to August 25. The open beta, available on all platforms including the Nintendo Switch 2 for the first time, will take place from August 28 to September 1.

The open beta does not require a preorder or access code. The game is set to launch on October 23. According to the official Call of Duty blog and reports from Windows Central, Activision has not yet specified a start time for the early access weekend, only noting that it begins immediately after this year's Call of Duty: NEXT broadcast.

How to Get Early Access to the Modern Warfare 4 Beta and When the Open Weekend Runs

The early access period from August 21 to August 25 is available only to players who preorder any edition of Modern Warfare 4 on Xbox Series X and S, PlayStation 5, or PC via Steam, Battle.net, or Xbox on PC. According to Windows Central, preorder-based early access does not apply to the Nintendo Switch 2, which is limited to the open beta weekend.

Some early access codes have also been sent to viewers of Call of Duty live stream events, including the Fanatics Fest showcase. Activision has not announced how the beta client will be distributed. Previous Call of Duty betas, such as those for Black Ops 6 and Black Ops 7, were delivered via updates through the Call of Duty HQ launcher.

The open beta is free and available on Xbox Series X and S, PlayStation 5, Nintendo Switch 2, and PC. No preorder or code is required to access it. Players can get in through the Call of Duty HQ launcher, which needs to be installed before the beta begins.

This marks the first time a Call of Duty beta includes the Nintendo Switch 2.
